An air source heat pump extracts heat from the outdoor air. This heat is used to warm water. The heated water is subsequently circulated through radiators or an underfloor heating system. This ensures that your rooms receive a consistently comfortable level of warmth. Additionally, it possesses the added capability of heating the water stored in a hot water cylinder, consequently supplying hot water for your taps, showers, and baths.
The process begins with the absorption of heat from the air into a special fluid. This fluid is then directed through a heat exchanger within the heat pump, where it undergoes a temperature increase before transferring this warmth to the water.”
